ION REMOVAL IN REVERSE OSMOSIS
WORKING PRINCIPLE
STAGES OF CLEAN WATER
PRODUCTION IN
REVERSE OSMOSIS SYSTEM
Feed water pressure must be minimum 3 bar for-
reverse osmosis system to work. If the feed water
pressure is not sufficient, the system can be rein-
forced with a pump.feed water passes through the
following filtrations respectively;
Ÿ
n)
1
st
Stage: 5 micron pp sediment filter. The
pre-sediment filter retains suspended materials
and particles in the water and protects succes-
sive filtrations, especially the membrane filter.
(1 mm=1000 micro .

.
2
nd
Stage: Activated carbon filter removes pol-
lutants, which are harmful to human health and
membrane filter, by retaining organic substances
and high amounts of cancerogenic chlorine and
chlorine compounds
Ÿ 3 rd stage: Block carbon filter is used for more
sensitive particle filtration to retain the suspen-
ded materials in the water.
Ÿ
4
th
stage: Membrane filter. The semi-permeable
membrane with 8-12 angstrom pores retains
bacteria, viruses and heavy metals in the water
at 95-98% and pollutant runs to the drainage
through wastewater part of membrane.
Ÿ 5
th
stage: Last carbon filter (post carbon). Water
runs through the carbon filter at the last stage to
provide clean and extremely safe drinking water.
